To all whom it may concern:

; Be it known that I, CLARKE P. POND, a

.citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements 1n VVIHdOW-OPGIfi'tlIlg Mechanism, of which the following is a speciin rods subjected to torsion.

fication. My invention relates to that particular class of mechanism particularly designed for l simultaneously 0 )6I1l11g or shutting a number of windows, shutters, or the like; one object of the invention being to provide operj ating means of such a! nature as to permit of a series of structures of the general. character noted being moved to oven or close them with the expenditure of less force than has 1' heretofore been required to perform a simil lar work.

Another object of the invention is to provid'e mechanism, whichfin addition to possessing the above noted charm-tcristics, shall be of such a nature that not only will all of the structures operatednpon be moved to an equal extent but the various parts shall utilize'to' the best advantage the force exerted upon. them.

' I' also desire to provide window. operating mechanism of the general type above noted, which shall bcsimple in consiruction, sure in action, and which shall not requircopcratlhese objects and other advantageous ends I secure as hereinafter set forth, refererice bcin had to the accompanying drawin s, in which:

igure 1, is a plan illustrating in horizontal section a part of a building and showing my invention arranged to operate a series of Windows, of which two are illustrated; Fig. 2, is a side elevation of the meclumism illustrated in Fig. 1; Fig. 3, is a vertical section taken on the line 3-3, Fig. 1; Fig. 4, is a vertical section on the line 4- l, Fig. 1; Fig. 5,,is a. plan illustrating the detail con .l1'1 the-above drawings, (l represents a. por tlon of the wall of alulldmg m which are ]')l d0((l window frames 0 which, in the preseht instance, are providedwith anumber of sashes mounted to swing on substantially horizontal axes. Two of these sashes are 111- dicated at c and c and these are ty ical of a. OJ

series of sashes of any desired num er.

Mounted upon the Wall of the buildin in any suitable manner is a frame D inclu ing a plate d in which is a bearing for a shaft a projecting per 'iendicularly from. the vertical 65,

face of the wall. The inner end of this shaft is mounted in .a step bearing d carried on a pivot pin (5*, which is suitably attached to the frame I) so as to lie adjacent to and sub stantially parallel with the face of the Wall.

The shaft (1 has fixed to it a wheel A having a. grooved periphery for the reception of an operating rope or chain and also ias mounted uhon it a pinion o Two toothed segments upon the pin J as an axis and are so formed as to lie parallel to each other with the pinion a/ between them and mesl'iing with tneir respective teeth. I

lnasmuch as the pin d is preferably mounted so as to extend in n vertical line, the two toothed segments B and B" operate in substantially horizlmtal. planes; there being pivotally attached to the first of the segand B are mounted so as to turn 75 ments one end of arod l) of any desired.

length, extendii'ig parallel to the face of the wall and adjacent to the line of windows to be operated. Similarly, the toothed segment B has pivotally attached to it one end of a rod l1 extending immediately under and 9 The substantially parallel with the rod 3).

connection between'each rod and its particular segment is so constructed that relativc movement between them 18 permitted on an axis substantially parallel to the pin 9 d The rod 6 has clamped or otl'ierwise fixed to it a series of collars l), which in turn are pivotally connected to levers 0. Each of these is fulcrurned at one end to a suitable supporting structure 0 fastened to the wall end of each lever'with the adjacent Window sash c; the construction between said lever and link being of sucha nature, as illustrated in Figs. 8 and 7, as to ermit of What is in effect a limited universe movement between said two parts. That is to say,a casting c is clamped to the link o but is so connected to the lever c as to permit said parts to move relatively to each other on a bolt 0 as an axis, while at the same time the connection between the lever and the casting c is such as to permit of a limited movement of the link 0 in any of a number of planes including the line of the bolt 0*. In addition to the levers 0 there is a second set of levers c, each connected by a clamp or collar 1) to the rod l) and having its end bent toward the end of that one of the levers c which is mounted to operate on the same window. That is to say, each of the windows to be operatedhas a pair of levers c and 0 respectively mounted on the frame at the sides or edges of the window and having their free ends bent towards each other. The levers c are likewise connected to the window sashes c 0 each by a link 0 attached to it by the means illustrated in Figs. 8 and 7.

The connection between each link 0 and the window sash is preferably made through the medium of the structure illustrated in Figs. 6 and 5, wherein e represents a casting or other suitable metallic piece fixed to the window and provided with two projecting lugs 6 between which extends a pin e. Both lugs have formed on their adjacent faces substantially conical projections through the centers of which the pin e extends in suchmanner as to provide a pivotal support for the connection of the link 0''. This link is loosly fitted on the pin 6 in order to permit of a sidewise movement in addition to its pivotal movement upon the pin a and the conical projections limit the link to a definite position on said pin so as to prevent its sliding to one side or the other and consequent bending, when the device is operated.

With the above described arrangement of parts, it will be understood that revolution of the chain wheel A in the direction of the arrow, Fig. 2, will move the rods 1) and b in opposite directions, while at the same time their points of connection with the toothed segments B and B will move around the pin as an axis so as to approach the wall of the building. Inasmuch, however, as the various other points of support of the rods 7) and b, as provided by the levers c and c, are pivotally mounted, both rods are moved )odily arallel to themselves toward the wall of the )uilding; it being noted that the distance from the points of support of the various levers to collars?) and b is the same as the distance between the pin (Z and the points of attachment of the rods b and I) to the reis such that this push takes place in the most direct manner, until finally, when the various parts occupy the )ositions illustrated. in dotted lines, the lin s 0 lie in planes sub stantially at right angles to the line of the walls or to the line of the series of windows. Likewise, the longitudinal and parallel movement of the rod 12 turns the levers of, on their pivots in a direction opposite to that taken by the lever c, with the result that they also transmit a direct Ipush to their respective windows through t ieir links 0 and act with them to open said windows. By reason of this )eculiar arrangement of parts, lam enablet to connect one set of the linksnc set of links through the levers c to oints ad jacent to'their opposite edges, so t rat under operating conditions each window is operated on equally by a force transmitted from the two rods b and b. tubular under practical working conditions, as are the links 0 As illustrated inFig. 9, it is obvious that a suitable endless cable'G may be substituted for the rods 1) and b, in which case said cable would be. provided with supporting pulleys F and F at its ends, so mounted on frames These rods are usually and F as to be free to swing toward and from the wall of the building as the windows are opened and closed; its upper run 9 being connected to all of the levers 0, while its lower run q is similarly connected to the levers c. In Figs. 9 and-l0, I have shown these frames F free to swing to a limited extent toward and from the Wall on a rodf as a pivot. Fixed tothe shaft a as shown in Fig. 10, isa s 1 ocl'ret wheel f around which passes a sproc et chain] having its ends respectively attached to the end of the rods 1) and I), while the opposite ends of said rods are similarly connected by a cable or chain f passing over a wheel f mounted ona'sha'ft As before, revolu- Y tion of the chain whee causes movement of the rods 11 and l) in opposite directions: the frame F sv. inging toward or from the wall as required by the position of the said rods.

By the provision of the various joints illustrated in Figs. 5'to 8 inclusive, the various parts ofniy device are free to move so as to accommodate themselves to the varying positions of the windows caused by the points or attachment of the links c moving in the arcs of circles and bythe slight up and down movement of the links 0 where these are connected with the levers c and c.

Vl'hile l have illustrated my invention as .applicd particularly to a series of 'wimlows,

it is to be understood that it is equally ap phi-able for the operation of shutters, or.
